Internally stock. I have a few extras and a hardshell for it. Custom amp, makes it really loud. Make me some kind of crazy trade offer I just want a different pistol to use lol. Has something going on where it shoot full auto sometimes so this might need retiring to full time showpiece soon... With a double action trigger, you can be entertained all day. This gun is like 12 years old and built like a tank, full metal everything basically.
